So what I have seen is:
warp to: only works sometimes, mostly brings me into a paradox of myself
warp in: same thing
warp to any: this seems to be working properly, and allows me to warp to things that "warp to" would just lead me to warping into myself
warp in any: same as warp to any, works as described
warp anywhere: works as described
I also tested it with "enter any" and it allows me to actually enter the vessel that I typed rather than a different vessel in the same space (example: if i typed "enter box" I would enter the "cat," but saying "enter any box" would actually bring me into the box)
